Gardening on the Moon: An Advection-Diffusion Model to Guide the Search for Supernova Debris in the Lunar Regolith / Costello, Emily S. (U. Hawaii (main)) ; Ellis, John (CERN ; King's Coll. London (main)) ; Fields, Brian D. (Illinois U., Urbana (main)) ; Surman, Rebecca (U. Notre Dame (main)) ; Wang, Xilu (CAS, Beijing)
The vertical redistribution of materials in the lunar regolith - ranging from continuously produced space-weathering products to sporadic pulses of supernova- or kilonova-derived isotopes - remains a fundamental problem in planetary science. [...]

A first study of strong isospin breaking effects in lattice QCD using truncated polynomials / Albandea, David (Helmholtz Inst., Mainz ; Darmstadt, GSI) ; Kuberski, Simon (CERN) ; Panadero, Fernando P. (Madrid, IFT)
Computing derivatives of observables with respect to parameters of the theory is a powerful tool in lattice QCD, as it allows the study of physical effects not directly accessible in the original Monte Carlo simulation. [...]

Influence of tides and self-gravity on Ultra-Light Dark Matter Bounds from Dwarf Galaxies / Caputo, Andrea (CERN ; Weizmann Inst. ; U. Rome La Sapienza (main) ; INFN, Rome) ; Teodori, Luca (IAC, La Laguna ; Laguna U., Tenerife)
Dwarf spheroidal galaxies provide some of the most sensitive astrophysical probes of ultra-light dark matter (ULDM), but the inferred constraints can be affected by two important systematics: tidal interactions with the Milky Way, which reduce ULDM-induced dynamical heating, and stellar self-gravity, which can become relevant if the stellar component was more compact at earlier times.
